A kind of general gravure printing roller
Technical field
The present invention relates to the printing machinery technical field, particularly a kind of gravure printing roller of intaglio printing press that can be general.
Background technology
Intaglio printing press is that the intaglio printing press print principle is the picture and text part that printing ink riddles gravure, printing ink is transferred to the process of reel printable fabric by the pressure of roller platen and gravure printing roller for the equipment of reel printable fabric printing.
Gravure printing roller is mainly by following two kinds at present, and a kind of is the solid version of tape spool roller, and its operation principle is: gravure printing roller is contained on the moveable carriage, moveable carriage is stuck in the fixed position of intaglio printing press again, printing is finished in gravure printing roller and roller platen pressing; Another kind is tape spool hollow version roller not, and its operation principle is: gravure printing roller directly is contained on the intaglio printing press, moveable carriage is stuck in the fixed position of intaglio printing press, printing is finished in gravure printing roller and roller platen pressing.More than two kinds of gravure because of can not be general, easily cause the waste resource, increase cost.After making, existing gravure can only be applicable to a certain type, adopt multiple gravure type printing with a kind of printed matter, even forme is the same, it is suitable with corresponding gravure type respectively also to need to make a plurality of editions rollers, so just waste resource, increased entreprise cost.
Summary of the invention
The invention provides a kind of general gravure printing roller, solve the wasting of resources that existing intaglio printing press can not generally cause because of gravure printing roller, the problem that cost increases.
Technical scheme of the present invention is achieved in that a kind of general gravure printing roller, comprises gravure axle and hollow gravure printing roller, and hollow gravure printing roller is sleeved on the gravure axle, and the gravure shaft end is provided with take-up.
Wherein, preferably, described take-up is arranged on described gravure axle one end, and the other end of gravure axle is set with and the integrated taper hole of gravure axle.
Wherein, preferably, described take-up is arranged on described gravure axle two ends.
Wherein, preferably, described take-up comprises taper hole and nut, and taper hole is sleeved on hollow gravure printing roller end, and the fixed by nut by being sleeved on the gravure axle is on the gravure axle.
Wherein, preferably, the length of described hollow gravure printing roller is 850~920mm.
Beneficial effect of the present invention:
1. break away from intaglio printing press because of gravure printing roller can not be general limitation, increase the flexibility of scheduling of production.
2. an intaglio printing press breaks down in the time of can not in time repairing therein, can not cause the stopping production of some product.
3. save the plate-making expense, improved gravure printing roller is hollow version, and every than cheap about 4000 yuan of the solid version of tape spool, if by 20 of plate-making in every month, can save nearly 1,000,000 yuan of the expense of plate-making every year.
4. the transfer performance of every intaglio printing press, printing effect, power consumption situation are all different, can optionally arrange product according to the characteristics of intaglio printing press after gravure printing roller is general, thereby can improve printing quality, reduce loss, and accomplish to save energy and reduce the cost.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is hollow gravure printing roller structural representation;
Fig. 2 is the general gravure printing roller structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiment that obtain under the creative work prerequisite.
As depicted in figs. 1 and 2, present embodiment provides a kind of general gravure printing roller, comprises gravure axle 2 and hollow gravure printing roller 1, and hollow gravure printing roller 1 is sleeved on the gravure axle 2, and gravure axle 2 ends are provided with take-up.
Wherein, take-up comprises taper hole 4 and nut 3, and taper hole 4 is sleeved on hollow gravure printing roller 1 end, is fixed on the gravure axle 2 by the nut 3 that is sleeved on gravure axle 2.
Tight device is arranged on described gravure axle one end, and the other end of gravure axle 2 is set with and gravure axle 2 integrated taper holes 3.Taper hole plays the effect of fixed cover, and fixed cover is designed to truncated ordinary cone, and one of them and the machine-shaping of middle heart axle one, makes like this to be connected compactlyer between hollow gravure printing roller and the gravure axle, is conducive to improve printing precision.
The take-up setting also can be arranged on gravure axle two ends, and at the dimensions of different type of machines, it is more convenient to be suitable for like this.
In the present embodiment, the length of hollow gravure printing roller is 870mm, and the length of hollow gravure printing roller is not limited thereto, and can make different sizes according to the size of different type of machines, and the length of general hollow gravure printing roller is 850~920mm.
Assembling process: the gravure axle is packed in the hollow gravure printing roller, insert taper hole at the gravure axle then, tightening nuts can be finished the assembling process of hollow gravure printing roller.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
